Ward served in the Arizona state Senate for nearly three years, before resigning to challenge Arizona Sen. John McCain for U.S. Senate in the 2016 Republican Party. The following year, she decided to run for Senate again against Jeff Flake before losing to Rep. Martha McSally in the 2018 Senate primary.

Ward came under fire for insensitive comments she made following McCain’s death and has a history of promoting conspiracy theories.

Ward’s election comes as the traditionally Republican state continues to turn purple. Arizona will likely be a crucial battleground state in the 2020 presidential race and will also feature one of the most hotly contested Senate races in the country when appointed Republican Sen. Martha McSally is expected to run to finish out McCain’s term.

McSally lost to now Democratic Sen. Kyrsten Sinema in 2018 in what was one of the tightest midterm races in the country.
